extractData accesses the super-global variable $_SESSION.
Open

    protected function extractData($fields)
    {
        if ($this->readCallback !== null) {
            if (!isset($fields['data'])) {
                $fields['data'] = '';

Superglobals

Since: 0.2

Accessing a super-global variable directly is considered a bad practice. These variables should be encapsulated in objects that are provided by a framework, for instance.

Example

class Foo {
    public function bar() {
        $name = $_POST['foo'];
    }
}
